  Move uminor() and umajor() to the same place as userspace minor() and major().
  
  The uminor() and umajor() functions have the same use in kernel space as
  the minor() and major() functions in userspace. If we ever get rid of
  the minor() function in kernel space, we could decide to just expose
  minor() and major() to kernel space, making uminor() and umajor()
  redundant.
  
  There are two reasons why we want to have uminor() and umajor() in
  <sys/types.h>:
  
  - Having them close together prevents them from diverting. Even though
    it's unlikely the definitions will change, it's a good habit to have
    them at the same place.
  
  - They don't really belong in kern_conf.c. kern_conf.c has been
    liberated from dealing with device major and minor number handling.
  
  The device_ids(9) manpage now lists the wrong #include's, because it
  should only list <sys/types.h> now. I'm leaving it as it is now, because
  I wonder if we should document them anyway. We're probably better off
  documenting minor(3) and major(3).
